Book excerpt: Ammonium perchlorate's burning rate as a function of pressure has an exponent break around 4000 psi where the pressure exponent becomes greater than 1. This causes AP to be highly sensitive to pressure fluctuations that can damage or destroy ammonium perchlorate composite propellant-based solid rocket motors. Studies conducted on AP at these high pressure are few and there is a lack of direct qualitative data due to the challenges posed by the high-pressure environment and optical window structural limitations. This has left the cause exponent break mechanism unknown and difficult to study. The High-Pressure Combustion Lab has built an Ultra-High Pressure Optical Chamber (UHPOC) that allows for optical measurements at these higher pressure regimes. Testing visual measurement techniques using the UHPOC and a telescope zoom lens to take detailed images of the propellant surface during the burn was conducted. Non-aluminized propellant and aluminized propellant samples were tested to observe the mechanisms of aluminum particle combustion in a propellant at high pressures and the behavior of the propellant past the exponent break region. \par At atmospheric, detailed high-speed images on the propellant surface were obtained using a high-powered lamp to light the surface brighter than the flame. At higher pressures, however, the luminosity of the flame was significantly greater than the lamp, creating shadow images of the propellant. Binder agglomerates were observed coming off the surface which increased in size and magnitude as the pressure increased. This is attributed to AP decomposition becoming the dominant burning rate mechanism which burned faster than the surrounding binder as has been observed from previous studies and numerical models. This leaves the binder only partially pyrolyzed, forming the agglomerates which detached from the surface. Aluminum particles were found to ignite at all pressures with the binder agglomerating the same amount in both aluminized and non-aluminized samples. Atmospheric tests show aluminum particles with detached flames and high-pressure tests show aluminum particles with surface flames.

Download or read book A Simulation Study of the Combustion Mechanism of Aluminum in Solid Rocket Propellant at High Temperatures and Pressures in a Shock Tube written by Zichao Liu and published by . This book was released on 1986 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of aluminum combustion in pure oxygen and mixture (N2-H2- Cl2-O2) at high temperatures and pressures provides a simulation of combustion mechanism study of aluminum powder in solid rocket propellant. Computations were performed for predicting possible intermediate species and products. Emission spectra of important intermediate species were identified by using a spectrometer. Time histories of the AlO emission band show the continuum radiation of Al2O2 in the reaction scheme. The solid and liquid products were observed and analyzed by electron diffraction, X ray diffraction, transmission and scanning electron microscopes. The gaseous products were detected by using infrared spectrometry. These measurements are in good agreement with the computations and provide useful chemical kinetic data. Keywords: Mathematical prediction, Aluminized propellants, Aluminum oxides. (Chinese translations).

Book Synopsis Design and Implementation of an Emission Spectroscopy Diagnostic in a High-pressure Strand Burner for the Study of Solid Propellant Combustion by : Jason Christopher Arvanetes
Download or read book Design and Implementation of an Emission Spectroscopy Diagnostic in a High-pressure Strand Burner for the Study of Solid Propellant Combustion written by Jason Christopher Arvanetes and published by . This book was released on 2006 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each propellant was combusted in a controlled, non-reactive environment at a range of pressures between 250 and 2000 psi. The data allow for accurate burning rate calculations as well as an opportunity to analyze the combustion region through the emission spectroscopy diagnostic. It is shown that the new diagnostic identifies the differences between the aluminized and non-aluminized propellants through the appearance of aluminum oxide emission bands. Anomalies during a burn are also verified through the optical emission spectral data collected.

Download or read book Holographic Investigation of Solid Propellant Combustion Particles written by Peter J. Mellin and published by . This book was released on 1983 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: This investigation continued the development of a method for obtaining high quality holograms of the combustion products from aluminized solid rocket motor propellants burned in a two-dimensional motor to provide a cross-flow environment. The use of glass side plates as a motor casing provided both a convenient construction technique and allowed good quality holograms to be obtained. At combustion pressures above 500 psia and propellant slab thicknesses greater than 0.080 inches, the timing of the laser pulse during the burn was found to be critical, since an extremely short time interval existed between the establishment of steady state slab burning and the generation of too much smoke/combustion products to permit laser penetration. As desired operating pressures increase and aluminum powder particle sizes decrease, it will probably be necessary to use thinner propellant slabs. (Author).
